ELECTRICAL SPECIFICATIONS
Specifications with standard type are for an Operating Temperature of T A = 25°C only. Minimum and Maximum limits are
guaranteed through test, design, or statistical correlation. Typical values represent the most likely parametric norm at T A =
25°C, and are provided for reference purposes only. Unless otherwise indicated, V CC = 5.0V, T A = –40°C to 85°C.

Note 1: Low duty cycle pulse techniques are used during the test program to maintain junction temperature as close to
ambient temperature as possible.
Note 2: If the output switch is driven into hard saturation (non-Darlington configuration) at low switch currents ( ≤ 300mA)
and high driver currents ( ≥ 30mA), it may take up to 2.0 μ s for it to come out of saturation. This condition will shorten the
